You can see the full results below plus the regional breakdown; they even have a fancy little graphic. England overall had a thin majority on leave, with Scotland, N. Ireland and Gibraltar all voting to remain. Wales was a bit of a mixed bag, with some remain and some leave areas.
The whole thing has been a bit of a disaster; none of the leavers can agree on what they actually want to leave (common market vs separate, freedom of movement vs controlled access etc) and there is basically no permutation that they can all agree on, or are putting forth ludicrous demands to the EU that make no sense.
Additionally, there were a number of issues with the leave campaign playing dirty pool; they've overspent, they told outright lies about what was possible, and then there is the entire 'Cambridge Analytica' affair. There is also a pretty strong undercurrent of nationalism and 'keep the immigrants out' that was part of the campaign, so it's pretty ugly.
Their economy is so completely intertwined with the EU and they are so used to no borders that a no-deal (and the inevitable subsequent border checks when they leave the common market) that it will literally wipe out entire industries in the UK without massive subsidization. For example, something like 90% of the sheep they raise go to the EU, and over 60% of farmer's income currently comes from the EU subsidies. The London financial sector has taken a big hit with all the relocations (which will likely accelerate with a no-deal) and all kinds of manufacturers have announced shut downs as they relocate to the EU so they can keep their supply chain in the common market and avoid intermediate tariffs. Even the stuff that is wholely made in the UK relies heavily on EU products, so there will be an increase across the board in prices. When this is tied with the value of the pound dropping, doesn't take a genius economist to know this will be particularly brutal for anyone that isn't wealthy. Once everything craters it's a great opportunity for anyone with a lot of capitol to buy up assets at rock bottom prices and sit on them for a decade while things recover, but that doesn't help the millions that are just getting by now.
The prorogation really has a lot more to do with pushing a no deal Brexit through then it does politics and the Tories getting re-elected; Johnson's cabal started as an election team and this was kind of their plan all along. If they had kept Parliament in session, probably even odds that nothing much would have changed and they would be at risk of going to the polls without any kind of Brexit, so this way they can force the issue, delay Brexit again, get an election where they can position themselves as the Brexit party, and get back in; otherwise they would likely have been decimated for either not delivering, or after the no-deal effects are felt. It's pretty gross and overt politics with the sole goal of staying in power, regardless of the cost to the country.
Think if they had figured out a withdrawal agreement it still would have been painful, but they would have muddled through. In case of a no-deal, very real possibility of Scotland leaving the UK, N. Ireland descending back into the Troubles, and possibly Gibraltar going independent as well.
Defence, policing etc is also all heavily entwined with the EU, so there are some fairly significant security concerns as well. Did think it was pretty funny that the UK wanted a EU naval taskforce for the straights of Hormuz; just shows how self centered and out of touch these useless toffs in charge are.
